What is being argued by the OP is forced content. Forced raiding to continue with the game's story. If you don't raid, then you do not progress further in the game. That is forced content. Currently, GW2 doesn't have this model and I don't believe that they intend to change to one like that now. As for people posting and asking for more challenging content, that's how raids were brought about in the first place. Now, if the current raid structure is not challenging enough for those players, then certainly they can ask for raids to be made harder. Heck, they're welcome to it! My problem with the suggestion in this thread is forcing all of the player base to endure this harder raid content in order to progress.
